The specific adsorption of polar molecules in AlPO4-5 is caused by the nonsymmetric lattice structure of the crystals. This has been proven using scanning pyroelectric
microscopy (SPEM). This novel technique provides information about both the zeolite structure and the orientation of adsorbed polar molecules.
